卫星通信中数字调相信号调制方式识别方法研究
说明: 针对数字卫星常用的 7 种通信信号调制方式(QPSK、8PSK、16QAM、32QAM、64QAM、16APSK、32APSK),对零中心归一化瞬时幅度谱密度最大值、四次方谱、幅度、高阶累积量四种特征参数进行了分析,提出了一种联合特征参数的信号调制识别方法.(Aiming at seven communication signal modulation modes commonly used in digital satellite (QPSK, 8PSK, 16QAM, 32QAM, 64QAM, 16APSK and 32APSK), four characteristic parameters of zero-center normalized instantaneous amplitude spectral density, quadratic spectrum, amplitude and high-order cumulant are analyzed, and a signal modulation recognition method of joint characteristic parameters is proposed. Method.)

Study-on-the-Control-Scheme
恒频恒压(CVCF)逆变电源的输出电压波形质量是衡量其性能的重要指标之一。文章采用一种重复控制和双闭环控制相结合的电压波形控制策略,以重复控制器提高逆变电源输出电压的稳态精度,减小总谐波畸变率;以双闭环控制器达到较快的动态响应速度。该方案在一台采用TMS320F240 DSP控制芯片的50 Hz三相PWM逆变器上得到验证。(Constant voltage constant frequency (CVCF) Inverter output voltage waveform quality is an important measure of its performance indicators. Paper using a repetitive control and the combination of double closed loop control voltage waveform control strategy to improve the repetitive controller output voltage inverter steady-state accuracy and reduce total harmonic distortion to achieve a faster dual-loop controller dynamic response speed. The program uses TMS320F240 DSP in a 50 Hz phase control chip PWM inverter has been to verify.)
